To all 2071077; it. may concern.

Be itilrnown that we, lioenn'r and Gannon C. Henri-mar, citizens ot-the United States, residing in the cityotv Los Angeles, county of Los Angeles and State of (laliitornia, have inventcdcertain new and useful improvements in MateriaLCompressing ltlaehines, of which the 'l ollowingis a specification.

Our invention relates to certain improvements ininachines at the character referred to, and asshown and described in U. S. Letters Patentiiumber 1,260,514, issued to said Robert ii. lolelnan, March 26th, 1918. The object of the present invention is to provide certain improvements in the mechanism. which l deternnnes the length of the corn pressed article, and trips, or controls the mechanism which cuts, ties and? discharges the finished article from the-machine.

In order to describe our invention, we have shown on the accompanying three sheets of drawings so much otthe general machine asis necessaryto illustratethe invention of the present application and its connection to the ln' aehine. proper, for a. description of which reference is made to the patent above referred to;

In the present drawings- Figure 1 is a front elevation of a compressing machine, embodying the present invention Figure 21s an enlarged view of the mechanism comprising the present invention;

Figure 3 is a similar view looking at the left hand side of the mechanism shown in Fig. 2; V

Figure lis a view looking at the right han d side of the mechanism shown in Fig. 2;

Figure 5 is a view looking at the right hand side of the upper part of Fig. 4;

Figure 6 is an edge view of a yieldingly supported yoke for the lower pivoted ends of two breaker aws or men'ibers-t'or biting oiii thebloc ks of the material as his forced down through the lower ends of the forming dies; and,

' Figure 7 is a top plan view of a. yoke for holding the forming dies or receiving mem bers, tor the material being compressed.

Referring now in detail to the drawings,

B. Cor- MA r7 and moreparticularly to 'Figure 1, the parts of the main machine necessary to be here referred to, comprise the two tamping bars 1--l, the machine here illustrated being duplex machine, the opposite sides of which are alike. 7

Two vertical guide bars 2 2, guide two reciprocating heads 3-3, which operate said tamping bars 1+1. Thematerial to be compressed is discharged into the hopper members 1 4, and is forced by the tainping bars l--l, down into the dies or forming members 5-5, held in the yokes 6-6, having two embracing rings, 6 -6 adapted to beheld in adjusted positions by means of a screw 7, and a lock nut 8,shown in plan view in Fig. 7. By means of these yokes, said dies, or forming members 5, 5, can be regulated as to the resistance with which they hold the stick of material being compressed herebetween, and by turning the screw 7, oneway or the. other, the pressure of said forming members on the material can be increased or reduced, and a much stronger device is provided, and all the strain is taken oft the end of the machine frame.

Mounted on the reciprocating head 3, is

an arm 9, which moves up and down with;

said .head 3, adjacent a vertically movable trip or cam bar, 10, shown in three views in Figs. 2, 3 and 4;. Set in one side otsaid trip bar 10, is a hinged latch member 10?,

the lower end of which is adapted to be moved outwardly into the path of the arm 9, by means ota spring 11, attached to a yoke member 1 2, projecting from said latch m.en1be1-,-l0, around the opposite side of said bar 10, and resting normally on a member 13, pivoted at 14, to a plate 15, secured to a part of the frame member, 16.. Said pivoted member, 13, is normally held drawn toward the cam bar 10, by a spring 17, attached thereto at 17 above the pivot point 14, and to the plate 15, as at 17", below said pivot. Pivotally mounted on one side of the member 13, as shown in Fig. 5, is an escapement member 18, the lower end 18*, ofwhich is adapted to be engaged bya pivoted lever 19, on the trip bar 10, so that when the outer end of said lever .19, is pulled downwardly, its

other end, 19, will move upwardly, and enorros ans-mans, oanrnonnrans- 3:5 GNM gage the lower end 13, of the member 18, causing said member 18, and the member 13, to be moved outwardly from under the yoke member 12, whereby its spring 11, will operate to more said yoke member, 12, toward the bar iii, and thus more the latch member 10, outwardly into the path of the arm 9, as shown at the right hand side of Fig. 1, whereupon the next upward movement of said arm 9, with the tamping head 3, will engage said latch member 10, and lift the bar 10. The lifting of said bar 10, rocks at its lower end a rocker member 20, engaged by a pin 21, on the lower end of said bar 10, but as this relates to mechanism not fully disclosed, or claimed, in this application,

, further description thereof is not necessary,

said mechanism being fully disclosed and described. in the l S. iitent hereinbefore referred to.

The escapement member 18, is held in its normal position by means of a flat spring 18, On the next d wnward stroke of the arm 9, the yoke 12, engages the upper end of the member 13, and said latch member 10 is moved to its normal position in the bar 10, and out of the path of travel of said arm 9. The purpose of this trip bar 10, is to operate the rocker member 20, intermittently, and also to raise and lower a cam mechanism 10*, which operates a thrust rod (not shown) but described in the patent referred to.

A saw-like member 21 is mounted so as to engage, through a slot in the forming dies, 55, Fig. 2, with the block being formed and forced down through said dies, or holding member 55, so that the movement downwardly of the block with each tamping stroke turns said saw-like member 21 a partial turn. On the side of said sawlike member 21, are spaced pins 22, adapted to engage the free end of a lever 23, pivotally mounted at 2 1, on a bracket or hanger, 25, the opposite end of said lever 23, being pivotally connected, as at 26, to the lower end of a bar 27, sliding through a bracket 28, and the upper end of which bar 27, is provided with a pivoted dog or hook 29, hold in its normal position by means of a spring 30. A spring 31, is attached to a pin on said bar 27, and at its upper end said spring is attached to a pin 33, in the bracket 28, said spring operating to move said bar 27, upwardly as the free end of the lever 23, is released step by step by the pins 22, on the saw-like member 21, as it is about to be released in Fig. 1. As said bar 27, is thus moved upwardly by its spring 31, its hook or 29, catches on the member 19 above it, shown in Fig. 5, and the further downward movement of said bar 31, by the next pin 22, on the saw-like member 21, which has almost immediately engaged the lever will operate to pull the member 19, downwardly at its outer end, while its inner end rises and moves the member 13, and the member 13, on its pivot 14:, until the yoke 12, is again released, and the latch member 10, is moved outwardly by the spring 11, into the path of the arm 9, whereby said bar 10, is again lifted on the net up stroke of the arm 9. Also mounted on the side of the bar 10 is a bracket 34-, in position to be engaged by the arm 9, on its down stroke whereby said trip member 10, is positively moved downward to its proper stop position, Fi 2, by the reciprocating arm 9.

It will be understood that the machine is being constantly driven through the big gear G, from any suitable source of power and that the heads 33, are reciprocating the tamping bars, 11, with regular strokes, and that the briquets, or blocks, being formed and moved downwardly in the members 5-5, engage said saw-like member 21, and turn it step by step with each stroke of the tamping bar 1. This operates the trip bar 10 in the manner described, and 4 the trip bar, at its lower end, operates the rocker member 20, which in turn operates other mechanisms fully shown in the patent above referred to. The compressed ma terial is forced out through the lower ends of the forming members or dies 5, 5, into the upper ends of two breaker members or jaws, 3d, 3 1, pivoted together at their lower ends, as shown in Fig. 6, by means of pivot pins, 35, which also pivotally connect the two parts of a supporting band, 36. Said supporting band 36, is pivotally supported at its opposite sides by means of bars, 37, 37, movably anchored through the frame members, 38, 38, as clearly illustrated in Fig. 6, coiled springs, 39, 39, being mounted on said bars, 37, 37, and tensioned to normally hold said supporting band 36, and said aws or breaker members, 3-1, 34, in an upper position, but permitting their movement downwardly when the said jaws or breaker members are to be closed together at their upper ends, in'the manner clearly shown in the patent referred to, only the supporting means for said jaws or breaker members being considered necessary to be shown in the present drawings. This mechanism is also shown in Fig. 1.

By means of the improvements described and shown, the machine is made more accurate in its operation and more eilicient, and the tripping action through the trip bar 10, and its connections, is more positive and certain.
